Welcome to the forum. Lots of knowledge and great info here.
Now, I'm not a Moderator, and I don't play one on tv. This advice is based on past postings.
You'll get a bunch of interest in this, but there are some things that will make folks more comfortable. Post some photos, including one with a piece of paper with your forum name and current date with the gun. We've had a bunch of ne'er-do-wells try to get free money.
Folks like a photo showing the bore, too.
Best wishes with your sale, and welcome to a great site.
